It is widely recognized that future optical networks are moving toward a model wherein all-optical reconfigurable switching devices are interconnected to provide flexible and dynamic high-speed optical connections. Furthermore, the introduction of a common control plane represents a great challenge for achieving the required intelligence for efficiently(More)
Given the abundance and strategic importance of ring fiber-plants in metropolitan area networks, and the accelerating growth of Internet traffic, it is crucial to make use of recent advances in optical networking technologies such as WDM, ROADMs, OXCs and tunable transceivers in order to offer the most cost-efficient traffic transport. The objective of this(More)
Cloud-based radio access networks (C-RAN) are expected to face important challenges in the forthcoming fifth generation (5G) communication systems. For this reason, more flexible C-RAN architectures have recently been proposed in the literature, where the radio communication stack is partitioned and placed across different RAN nodes to tackle the 5G(More)
ns-3 is an open-source network simulator with support for simulating 3GPP LTE cellular network. This paper presents three extensions to the LTE module of ns-3, enhancing its capability of simulating scenarios with more sophisticated user mobility requirements. The first extension implements additional features in the UE measurements function. The second(More)
